Jan 14, 2020 how to prepare a bootable usb disk from 'InstallESD.dmg'? I have High Sierra correctly installed on my Mac. I need to clean install 'el capitan' on a old mac book pro (late 2011). I have 'el capitan' 'InstallESD.dmg' file. How to prepare a bootable usb disk? I've tried the 'restore' function in disk utility, selecting 'InstallESD.dmg' as source. OS X Recovery Disk Assistant v1.0. Built right into OS X, OS X Recovery lets you repair disks or reinstall OS X without the need for a physical disc. The OS X Recovery Disk Assistant lets you create OS X Recovery on an external drive that has all of the same capabilities as the built-in OS X Recovery: reinstall Lion or Mountain Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari.

DMG file is a disk image format created by Apple and massive used on Mac based computers. It can be converted to the ISO format using several different ways, but to burn it on to a DVD or CD to make it bootable is probably the best approach if you're only working with Mac systems. However, we've also covered how to burn a DMG file to a disk on Windows systems, in case that's what you have to work with.

Part 1: Burn DMG to CD/DVD on Mac via Command Line (Terminal)

The first method involves using command line executions to burn a DMG file to disk. In a Mac, this would be done in Terminal, which you can access in Applications >>Utilities >>Terminal. In Windows, it's the Command Prompt, which you can access by entering ‘cmd' in the run window.

Step 1: In Mac, enter the following command: hdiutil burn ~/Path/To/DiskImageFile

Use a Mac OS X installation Disc. If you’re unable to use Internet Recovery Mode or create a bootable USB installer, you can still use a Mac OS X installation disc. These discs are available for OS X Snow Leopard, OS X Lion, and OS X Mountain Lion. If your Mac is from 2012 or earlier, there was an installation disc in the original box.

Step 2 : Remember to replace the file name with the appropriate DMG file name.

Step 3 : The hdutil utility is quite powerful and will even let you create ISO files, and it's relevant for later versions of macOS like High Sierra or even El Capitan because you can't use Disk Utility to burn ISO to a USB drive. That's only possible on earlier Mac OS X versions prior to El Capitan.

In Windows, you'll need something like TransMac to directly burn DMG to a USB drive. We've described the process in the final section. It's a bit confusing because you don't have any options to burn the DMG to USB. You might end up wondering what to do unless you have a guide. We've shown you how to use it for this purpose in the final section.

Once the process is complete, remove the USB stick and use it to install the application associated with that DMG on any other Mac computer.

Part 2: How to Burn DMG to CD/DVD on Mac via DMG Editor

UUByte DMG Editor, as the name suggests, is an superb toolkit for handing DMG files on Windows and Mac computer. The stock burning feature can easily burn an DMG file to external CD, DVD or USB flash drive without taking much effort. Unlike other programs, there is no need to convert DMG to ISO.

The best part about DMG Editor is that disk partitioning is very easy since the software supports multiple file systems and partition schemes, which makes it much easier to use if you're not technically adept and knowledgeable about disk image files and how to handle them.

Part 3: How to Burn DMG to CD/DVD on Windows PC

TransMac is a little complicated to use, and you may not be very comfortable as a first time user. You'll get a 15-day trial when you install the utility, so if you're only doing a once-off, it should serve your needs.

Step 1: Install the TransMac software on your Windows PC. You can get the official download here.

Step 2: Before running the application, insert the USB drive, and then launch the app as Administrator.

Step 3: Right-click on the drive listed on the left side and choose 'Restore with Disk Image'. This will open up a new window where you choose the DMG file and click 'Ok' to proceed. The DMG file will now be burned to the drive you inserted.

TransMac is a great utility, but there are some things to keep in mind. First of all, you will need to do a GPT partition on your USB drive. That means you require some knowledge of the diskpart utility in Windows. If you're a novice, this is not a recommended approach. The better option would be to use DMG Editor after converting the file to ISO. It's faster and safer as well.

Burning DMG to DVD is much harder than burning ISO image becasue less tools available on the market. Fortunately, you can use DMG Editor and TransMac to burn the DMG file on Mac or Windows PC. They are the best two programs for DMG burning in 2018. So don't miss the tool when handing DMG files by yourself.
